Homeostasis (Keystone Species)

homeostasis (in an ecosystem)

• The number of different species in an area

• An environmental factor that prevents a population from increasing

• ecosystem has to maintain stable condition in order for all organisms to survive

• The removal of trees faster than forests can replace themselves.

cellular respiration

• Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen

• process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high-energy carbohydrates such as sugars and starches

• indirect effects in a community that are initiated by a predator

• Each step in a food chain or food web

keystone species

• a system of interlocking and interdependent food chains.

• All the living organisms that inhabit an environment

• A series of steps in which organisms transfer energy by eating and being eaten

• a species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically.

Photosynthesis

• Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen

• process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high-energy carbohydrates such as sugars and starches

• the series of processes by which carbon compounds are interconverted in the environment, chiefly involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.

• a species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically.

• An environmental factor that prevents a population from increasing

trophic cascade

• All the living organisms that inhabit an environment

• The number of different species in an area

• indirect effects in a community that are initiated by a predator
